While most of these circuits may interface directly to the RPi, the use of a buffered interface (such as the one supplied by the [[RPi Gertboard | Gertboard]]) is recommended which will help protect against damage. Alternatively, experiment with one of the [[RPi Tutorial Easy GPIO Hardware & Software#Alternative Test Platforms | Alternative Test Platforms]].

Extreme caution should be exercised when interfacing hardware at a low level, you may damage your RPi, your equipment and potentially yourself and others. Doing so is at your own risk!

Alternative Test Platforms

Until you have a RPi to test with, there are many alternative platforms available which will allow the testing of basic circuits. In addition, they may be interfaced with directly using the RPi in the future.
